Kinetic energy is given by KE = 1/2 m v^2. With a mass of 0.5 kg and speed 9 m/s, KE = 1/2 × 0.5 × 9^2 = 0.25 × 81 = 20.25 joules. The joule is kg·m^2/s^2, so this value makes sense for these numbers. The other options don’t fit because they would require either zero velocity (0 J) or different combinations of mass and speed that don’t match the given values; for this mass, 5 J would come from a much smaller speed, and 60 J would require a substantially larger speed.
